The air outlet flow can not blow human body forcibly after being dispersed and blown out, and is closer to natural wind, so that people feel more comfortable.

The embodiment of the utility model provides a wall-mounted air conditioner indoor unit. An indoor unit of a wall-mounted type air conditioner is an indoor part of a split wall-mounted type room air conditioner for conditioning indoor air, such as cooling/heating, dehumidifying, introducing fresh air, and the like.

Fig. 1 is a schematic structural view of a wall-mounted type air conditioning indoor unit according to an embodiment of the present invention; fig. 2 is a schematic cross-sectional enlarged view of the wall-mounted air conditioning indoor unit shown in fig. 1; fig. 3 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 2 when the flow divider 30 opens the air outlet 11.

As shown in fig. 1 to 3, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention may generally include a cabinet 10, a flow divider 30, and a wind deflector 60.

The front lower part of the casing 10 is provided with an air supply outlet 11 facing to the front lower part. Specifically, the casing 10 is a horizontally extending elongated shape, and has a substantially quadrangular cross section. The cabinet 10 may include a top wall, a front wall, a rear wall and a bottom wall and two transverse end walls, with the rear wall hanging against an indoor wall. The air supply opening 11 is located at the front lower part of the casing 10, and may specifically extend through the bottom of the front wall and the front of the bottom wall of the casing 10. The lateral or longitudinal direction of the housing 10 is indicated by x in the figure.

The air blowing port 11 blows an air flow in the casing 10 into the room to condition the indoor air. The air flow can be cold air produced by the wall-mounted air conditioner indoor unit in a refrigeration mode, hot air produced in a heating mode, or fresh air introduced in a fresh air mode, and the like.

The wall-mounted air conditioner indoor unit may be an indoor unit of an air conditioner that performs cooling/heating through a vapor compression refrigeration cycle system, and further includes a heat exchanger 40 and a cross-flow fan 50. The heat exchanger 40 is disposed in the casing 10, and is configured to exchange heat with an air flow flowing through the casing to form a heat exchange air flow, i.e., a cold air or a hot air, which may be a three-stage fin heat exchanger. The cross-flow fan 50 is disposed in the casing 10, and is configured to cause indoor air to enter the casing 10 through the air inlet 13 at the top of the casing 10, so that the indoor air exchanges heat with the heat exchanger 40 to become heat exchange air flow, and then cause the heat exchange air flow to flow through the air duct 20 to the air supply opening 11, and finally blow the air flow into the room through the air supply opening 11.

The flow divider 30 is disposed at the front side of the air blowing opening 11, so that the air flow of the air blowing opening 11 is blown toward the flow divider 30 and then divergently blown toward the indoor environment toward the edge of the flow divider 30 under the surface guidance of the flow divider 30. For example, in the embodiment shown in fig. 1 to 3, the number of the air blowing openings 11 is one, and the flow dividing member 30 is an elongated member whose length direction is parallel to the length direction x of the casing 10, and is a rod-shaped member parallel to the length direction of the air blowing openings 11. At this time, the outlet airflow is guided by the surface of the flow divider 30 and blown out toward both sides in the width direction (y direction) of the flow divider 30, that is, both sides in the width direction of the air blowing opening 11, that is, the outlet airflow is divided into two branches guided by the surface of the flow divider 30 and blown out upward and downward, respectively. Wherein, the air flow blown out upwards is upward flowing and flows to a higher and farther space; the downward blowing air flow sinks and flows to a lower and closer space, so that the air supply range is expanded. The rotation axis X of the air deflector 60 is parallel to the length direction X of the casing 10 and is located at the center of the width direction of the air deflector 60, so that the rotation range is wider and the air deflector can rotate by a larger angle without being interfered by the casing.

The air guide plate 60 is rotatably provided at a lower side of the air blowing port 11. The air guide plate 60 acts on the lower side of the air blowing port 11 to guide the direction of the outlet air flow. Of course, the air guide plate 60 may be rotated to a position where the air outlet 11 is shielded under the air outlet 11.

In the embodiment of the present invention, as shown in fig. 3, after the outlet airflow flows out from the air blowing port 11, the outlet airflow is blown to the flow divider 30 and the air deflector 60, instead of being directly blown to the indoor environment. The air current that blows to reposition of redundant personnel piece 30 is blown to indoor environment with dispersing towards the edge of reposition of redundant personnel piece 30 under the rear surface guide of reposition of redundant personnel piece 30, makes the air-out air current disperse more, and diffusion range is bigger for indoor refrigeration/heating speed is faster, and indoor temperature variation everywhere is more even, and the difference in temperature is littleer. The air outlet flow can not blow human body forcibly after being dispersed and blown out, and is closer to natural wind, so that people feel more comfortable.

Because the air supply opening 11 faces the front lower part and is simultaneously provided with the flow dividing piece 30 and the air guide plate 60, the air supply opening 11 can be designed to be larger, air outlet is smoother, and refrigerating and heating speed is higher. And the air supply can be carried out forwards and downwards, and the air supply requirements of different modes of refrigeration and heating are fully met. Moreover, no partition part is arranged between the air deflector 60 and the flow divider 30 to block the air flow, so that the flow loss of the outlet air flow is further reduced.

In addition, the air deflector 60 can be utilized to guide the downward air outlet direction of the air outlet flow so as to be beneficial to heating and downward blowing, and the air deflector 60 can be rotated to a proper angle so as to better guide the air flow to the flow dividing member 30 so as to be beneficial to better flow dividing and air supplying of the flow dividing member 30, and the design is very ingenious with reference to fig. 3.

The existing wall-mounted air conditioner indoor unit can better increase the air supply distance or enhance the direction guidance of the air outlet flow by more improving the direction, so that the air outlet flow is blown to a set area to achieve the aim of avoiding human bodies. The idea is creatively changed in the embodiment, the air outlet airflow is just blown out of the air supply opening 11, so that the air outlet airflow is diffused towards a plurality of directions (at least 2 directions), and the forward direct blowing strong airflow is avoided, so that the human body can be avoided, the cold quantity/heat quantity diffusion range is larger, and the indoor temperature difference is reduced. In addition, in the embodiment, the flow divider 30 replaces a conventional air deflector, and by dividing the flow, the flow velocity of the air flow is reduced, thereby avoiding that the air deflector and the surface of the casing 10 are not sufficiently cooled due to too high flow velocity, and the condensation occurs due to uneven temperature distribution. In addition, the shunt member 30 may be surface treated to increase the hydrophobic function of the surface and further prevent the surface from generating condensation.

Of course, in some alternative embodiments, the air outlet may also be round, square, rectangle with rounded corners, etc., and the splitter may be shaped accordingly, so that the outlet air flows outward along the radial direction of the splitter. And a plurality of air supply outlets arranged along the length direction of the casing can be further formed in the casing, and each air supply outlet is provided with an independent flow dividing piece and an air guide plate, which are not described in detail.

In some embodiments, referring to fig. 2 and 3, the splitter 30 may be mounted to the casing 10 to be movable back and forth to adjust the distance from the outlet 11, so as to adjust the air volume of the outlet 11. It will be appreciated that the closer the splitter 30 is to the outlet 11, the more the outlet 11 is blocked from the wind and the less the wind, but the stronger the splitter 30 is in its deflecting action on the outlet wind (causing the wind to be deflected towards its edges). When the flow divider 30 is farther from the air outlet 11, the air outlet from the air outlet 11 is smoother, and the air volume is larger, but the turning action on the air flow is weakened.

Further, the flow divider 30 and the air deflector 60 may be configured to be movable to a position for closing the air blowing opening 11 together, as shown in fig. 2, so as to prevent foreign matters such as dust from entering the casing 10 through the air blowing opening 11.

Fig. 4 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 2 in a down-blowing mode of operation; fig. 5 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 2 in a maximum blowing mode.

The embodiment of the utility model at least has the following air supply modes for users to select, and specifically comprises the following steps:

a forward air supply mode: as shown in fig. 3, the flow divider 30 is moved forward to open the air blowing port 11, and the air guide plate 60 is in a closed state or in a state of extending obliquely forward and upward as shown in fig. 3, and the air is divided forward by the air blowing port 11. When the air conditioner operates in the cooling mode, air can be supplied according to the air supply mode.

Downward air supply mode: as shown in fig. 4, the control flow divider 30 moves backward to shield the air blowing port 11, and the air guide plate 60 rotates to the open state to blow air downward. When the air conditioner operates in a heating mode, air can be supplied according to a lower air supply mode, so that the heating speed is accelerated. In this mode, the air deflector 60 can be in a vertically extending state, and the end of the air deflector is adjacent to the volute tongue 21 of the air duct 20, so as to guide the air flow to flow in a downward bending manner. After the airflow enters the air duct 20, the cross section is gradually increased to realize diffusion, the airflow is turned to be vertically downward under the action of the air deflector 60, and then the airflow passes through a tapered channel defined by the air deflector 60 and the volute 22 of the air duct 20 to realize acceleration before flowing out. Finally, the air quantity of the heating air supply is large, the air speed is high, the wind direction is vertical, the hot air can directly reach the ground, and the carpet type air supply effect is good.

The maximum air supply mode is as follows: as shown in fig. 5, both the flow divider 30 and the air guide plate 60 are opened, and the air outlet 11 is simultaneously opened forward and downward to maximize the air volume.

In some embodiments, as shown in fig. 2 and 3, the surface of the splitter 30 facing at least the supply outlet 11 may be convexly curved 32 to facilitate directing the airflow towards the edges of the splitter 30. Specifically, if the surface of the flow divider 30 facing the air outlet 11 is a plane, the air flow will turn 90 ° after blowing to the surface vertically, and then spread to the edge along the surface. The surface is made to be an outer convex curved surface in the embodiment, the air outlet flow impacts the outer convex curved surface 32 and then diffuses towards the edge along the outer convex curved surface 32, the air flow turning direction is less than 90 degrees, in the turning process, the direction is relatively more moderate due to the outer convex shape of the outer convex curved surface 32, and the air flow loss and the noise are smaller.

For example, in the embodiment shown in fig. 2 and 3, the air blowing opening 11 is elongated in a direction parallel to the longitudinal direction of the casing 10, and the flow divider 30 is rod-shaped in a direction parallel to the longitudinal direction of the air blowing opening 11. The two side surfaces of the flow dividing element 30 facing the air supply outlet 11 and facing away from the air supply outlet 11 are convex curved surfaces, namely a convex curved surface 32 and a convex curved surface 31, the joint of the convex curved surface and the convex curved surface forms two top ends A1 and A2, and the two top ends A1 and A2 can be provided with fillets, so that the outline of the cross section (the section perpendicular to the x axis) of the flow dividing element 30 forms an olive shape. This configuration of the shunt 30 is relatively simple and easy to manufacture, and also provides a more aesthetically pleasing appearance.

Specifically, as shown in fig. 2 and 3, the outwardly convex curved surface 32 of the flow dividing member 30 toward the air blowing port 11 may be formed by joining two circular arc surfaces CA1 and CA2, so that the outwardly convex curved surface 32, particularly the middle point C thereof, is more outwardly convex, thereby enabling the air flow blowing thereto to be more evenly divided to both sides of the point C. The convex curved surface 31 facing away from the air supply outlet 11 is a section of arc surface, so that the appearance is beautiful and the manufacture is convenient. The radiuses R1, R2 and the lengths of the arc surfaces CA1 and CA2 at both ends of the convex curved surface 32 can be further made equal, so that the air flows to the two parts tend to be equal. Of course, the cross-sectional profile of the shunt 30 can also be oval or other irregular shapes, and will not be described in detail herein. In some alternative embodiments, if the air supply opening and the flow dividing member are both circular, the convex curved surface may be in the shape of a spherical crown, which is not described herein again.

In some embodiments, referring to fig. 3, the casing 10 includes a volute tongue 21 and a volute 22 arranged in front and back, which together define an air duct 20, and an outlet of the air duct 20 forms the air supply outlet 11. The casing 10 of the present embodiment includes a framework for forming a basic frame of the indoor unit and body components such as a volute 22 and a volute tongue 21 for defining the air duct 20, and is not a pure air conditioning casing. A cross flow fan 50 having a length direction parallel to the length direction of the cabinet 10 is installed at an inlet of the air duct 20. The section of the volute tongue 21 connected with the air supply opening 11 is a divergent air outlet section sa which gradually inclines upwards from back to front. The shape of the volute tongue 21 enables the airflow to begin to spread towards the edge before flowing out of the air outlet 11, and is more beneficial to the spreading and blowing of the outlet airflow.

More specifically, the volute tongue 21 includes an air inlet section (kc), a middle section (cs) and an air outlet section (sa) in sequence from the inlet end to the outlet end thereof. Wherein the air inlet section (kc) extends from the inlet end (k) to the rear lower side. The middle section (cs) extends forward and downward from the end (c) of the air intake section (kc). The air outlet section (sa) extends forward and upward from the tail end(s) of the middle section (cs). The volute casing 22 is located behind the volute tongue 21 and is of a curved structure with a concave side facing forwards as a whole. The air outlet section (sa) can be further made into an inwards concave arc shape, and all the sections are in fillet transition, so that the direction of the air flow is changed more smoothly, and the flow loss is reduced.

As shown in fig. 2, the surface contour of the air outlet section sa of the air duct 20 can be matched with the surface contour of the corresponding section of the flow divider 30, so that the flow divider 30 is attached to the surface of the air outlet end sa of the air duct 2 in the closed state, which enables the flow divider 30 to better seal the air supply opening 11, and when the wall-mounted air conditioning indoor unit is in the non-operating state such as power-off or standby state, the flow divider 30 is moved to the closed state, and the flow divider 30 is also "embedded" into the air supply opening 11, so as to avoid the situation that the flow divider 30 is completely outside the air supply opening 11 and the appearance is affected. For example, when the flow divider 30 is olive-shaped, and the surface facing the air outlet 11 is the convex curved surface 32, the air outlet section sa is concave curved surface to match with it.

Fig. 6 is a schematic view of the drive mechanism of the diverter. Fig. 2 to 5 are views illustrating the wind path direction better and omitting the driving mechanism, and fig. 6 is a view illustrating the driving mechanism better and omitting the air deflector 60.

In some embodiments, as shown in fig. 6, the driving mechanism for driving the splitter 30 to translate back and forth is a rack and pinion mechanism, which is mounted to the lateral side of the enclosure 10 so as not to affect the airflow. The driving mechanism includes a rack 71 extending in the forward-backward direction and fixed to the splitter 30, a gear 72 engaged with the rack 71, and a motor 73 for driving the gear 72 to rotate to move the rack 71 forward and backward. The motor 73 may be fixed to the cabinet 10, and the rack 71 may be slidably installed to the cabinet 10 in the front and rear directions. The motor 73 is controllably reversible to enable the splitter 30 to translate back and forth in a reciprocating manner. The motor 73 may be a stepper motor.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the utility model may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the utility model. Accordingly, the scope of the utility model should be understood and interpreted to cover all such other variations or modifications.
